Application filed. June 3, 1912. Serial No. 701,338.

To all whom it may concern:

Be it known that L'FRANK P. MAIZE, a

citizen of the United States, residing at specification, reference being hadtherein to the accompanying drawing.

My invention relates to improvements in controller regulators, and more particularly to controllers used on electric railway cars. The object of my invention is to provide a controller of this character in which the controller arm or crank is regulated so that it cannot be moved instantaneously to a point on the controller where full power is obtained, but has to be turned from point to point as is well" understood by those skilled in the art.

Another object of my invention 1s to provide a simple, cheap and effective regulator which may be readily attached to the ordinary controller having certain details of.

structure more fully pointed out. p

In the accompanying draw1ngs-F1gure 1 is a top plan view of a controller box showing my device applied thereto, the working parts being shown in dotted lines. Fig. 2 1s a side elevation partly in section of Fig, 1. Fig. 3 is a vertical transverse sectional view taken on the line 3-3 Fig. 1. Fig. 4 is a side elevation similar to Fig. 1, showing the looking or controlling pawl in its locked position. Fig. 5 is a detached perspective view of the locking member. Fig. 6 is a vertical sectional view of the upper end of the controller box, showing my invention applied to the interior of the box and also showing a modified form of the locking member. Fig. 7 is a transverse vertical sectional view taken on the line 7-7 of Fig. 6. Fig. 8 is an end view of the locking member of the modified form shown in Figs. 6 and 7. 7

Referring now to the drawing, 1 represents the upper end of the controller box of the ordinary form now used on electric cars. The said controller box is provided with the controller shaft 2, extending upwardly through the upper end of the box. This controllershaft as is well understood by those skilled in the art is adapted to control the power of the motor.

Secured to the upper face of the motor is a plate or box-like member 3, having a centra-l opening 4, through which the controller shaft 2 freely passes. The said plate 3, as heretofore stated, is of a box-like form havmg the annular chamber 5 surrounding the shaft 2. Within the said annular chamber adlacent lts inner periphery and rigidly secured thereby, are the upwardly projecting lugs 6 having beveled faces 7. These lugs, as is well understood, represent the contact points of the motor and, as shown in Fig. 1, are elght in number. Within the annular chamber 5, adjacent its outer periphery, are lugs Shaving beveled faces 9, which correspond 1n number to the contact points 6, and are arranged in two groups, one group of three and the other group of four.

The annular central passage 4, through the member 3, has screwed thereon a washer 10, which is adapted to overlap the upper face 11 of the plate or housing 12. This housing, as is shown in Fig. 1, is provided with two upwardly extending lugs 13 and 14 between which extends the controller lever 15, carried by the upper end of the controller shaft 2. By this structure it will be seen that the plate or housing 12 is rotated with the controller lever or crank 15. The plate or housing 12 is provided with an elongated tangentially arranged housing 16 havlng its lower end communicating with the annular space 5 in the plate 3. The said housing 16 is provided with a transverse shaft-17 looked against rotation by the setscrew 18, and also held against longitudinal movement by the setscrew. Loosely mounted upon the shaft 17 midway its end is a lever 19. Said lever, as shown in Fig. 5, has an enlarged outer end 20 and a reduced end 21 whereby the enlarged end 20 overbalances the reduced end 21 and normally holds the lever in the position shown in Fig. 2 of the drawings. The lower edge of the lever 19 directly below the shaft is provided with a downwardly extended arm, 22, which extends within the annular space 5 and in a parallel line with the lugs 6. In Fig. 5 it will be seen that I have shown the arm 22 as separate from the lever 19 and bolted or riveted be-- tween cars 23 carried by said lever.

Mounted upon the shaft 17 beside the lever 19 is a segment lever 24, which has its outer end provided with downwardly ex-' engages the lugs 8, whereby the housing 12 is held against rotation and the controller by arm 15. The housing 16, as shown in Fig. 3, of the drawing, is of a width approximately that cf the two levers 19 and 21-. ll'ithin said housing is a ball 26, which rolls upon the upper edges of the levers 19 and 24 and is normally in the right-hand end of the housing 16, as shown in Fig. 2 of the drawing. hen in this position the ball overbalances the ends 21 and 25 of the levers 19 and 2d and holds them in the position shown in Fig. 2 of the drawing. hen the housing 12 is turned by the controller arm 15, the downwardly depending arm 22 of the lever 19 engages one of the lugs 6 and rocks said lever 19 which causes the ball to roll toward the left of Fig. 2. This ball in its travel to the left rolls upon the upper face of the lever 2%, and after it has passed its pivotal connection, causes said lever to swing downwardly and the dog-shaped end 25 engages one of the lugs 8 and the controller arm is locked against further movement. The arm 22 of the lever 19 having passed over the lug 6, the weighted end 20 overbalances the end 21 and the ball, and said ball is caused to travel to the right which again rocks the lever 24. withdrawing the dogshaped member 25 from engagement with the lug S, which releases the housing 12. The operation just described allows the controller arm 15 to be turned to the next lug 6, corresponding to the points on the controller and the operation is again repeated. By this structure it will be readily seen that it is impossible for the controller arm 15 to be turned more rapidly around, as itis necessary for the controller arm to come to a standstill for a short period at each lug 6, representing the points on the motor. This period of time at which the lever is held is very short as it is only necessary for the ball 26 to roll from the right-hand end of the housing 16 to the leftand back again. The housing 3 is provided with a setscrew 3 which is adapted to engage a lug 15' carried by the lower face of the controller arm 15, whereby the movement of the lever is controlled and regulated. In Figs. 6, 7 and 8 instead of having my improved device applied to the upper face of the controller box 1, I have shown it applied within the controller box. In this view, 2 is the controller shaft the same as shown in the preferred form and is provided with a controller arm. Carried by said controller shaft 2, within the controller box is a disk 27, keyed upon the shaft. The said disk is provided with the lugs 6 and also the lugs 8 corresponding to those shown in Figs. 1 and 2 of the drawing. Secured to the lower face of the upper end of l the controller box 1, is a downwardly del pending lug 28 in which is mounted a shaft 29, upon which is loosely mounted the housing 28. One end of the housing 28 is thickened as indicated at 30 and forms a dog adapted to engage the lugs 8, as will be hereinafter more fully described. Loosely pivoted upon the shaft 29, intermediate its ends, is a lever 31, which has its end 32 thickened so as to form a weight to overbalance the end 33. The said lever 31 directly below the shaft 29 is provided with a ratchet arm 34 ad: ted to engage the lugs 6, representing or indicating the points of the controller. The lever 30, as shown in Fig. 7 of the drawing, is of a width equal to the interior width of the housing 28. \Vithin the housing above the lever 31, is a ball 35 which rests upon the upper face of the lever and is normally held in the right-hand end of the housing 28. The rotation of the controller shaft 2 causes the disk 27 to r0- tate therewith and the arm 34 is engaged by one of the lugs 6. This causes the lever 31 to rock upon the shaft 29 throwing the weighted end of the lever upwardly, causing the ball to roll to the left and overbalance the housing 28 causing its thickened end 30 to move downwardly and engage one of the lugs 8, whereby the disk 27 and the shaft carrying the same are locked against rotation. The arm 31 of the lever 31 having passed the lug 6, the weighted end 32 causes the ball to roll to the right which overbalances the weighted end 30 of the housing 29 and unlocks the disk 27, as is readily seen from the drawings.

From the foregoing description, it will be seen that the controller arm cannot be rapidly turned, to turn on the current and thus prevent the car from being suddenly started. The beveled faces of the lugs 6 and 8 allow the controller arm to be swung rapidly around so that the current can be instantaneously cut off.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:
